摘　　要：比较了一系列4-芳亚甲基-2-苯基-1H-咪唑-5(4H)-酮类化合物在不同有机溶剂中紫外光谱和荧光光谱的变化,探索了其结构与光学性能之间的某些关系.通过实验发现,目标化合物4-芳亚甲基芳环取代基的不同对其紫外光谱、荧光发射光谱及荧光量子产率有一定的影响.The spectral characteristics of 4-arylidene-2-phenyl-1H-imidazol-5（4H）-ketone derivatives in different solvents are compared by investigating their UV and fluorescence spectra.The relationship between the compounds structure and their optical properties was investigated.The data indicate that the different substituents on the 4-arylidene ring presenting in position 4 of imidazol-5（4H）-ketones have important influence on their UV spectra,fluorescence spectra and fluorescence quantum yields.
